  2. Electrical system of the International Space Station - Wikipedia

    en.wikipedia.org/wiki/Electrical_system_of_the...

    The electrical system of the International Space Station is a critical resource for the International Space Station (ISS) because it allows the crew to live comfortably, to safely operate the station, and to perform scientific experiments. The ISS electrical system uses solar cells to directly convert sunlight to electricity.

  3. Solar panel - Wikipedia

    en.wikipedia.org/wiki/Solar_panel

    A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. The electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.

  4. Power system protection - Wikipedia

    en.wikipedia.org/wiki/Power_system_protection

    Power system protection. Power system protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults [citation needed] through the disconnection of faulted parts from the rest of the electrical network. The objective of a protection scheme is to keep the power system stable by ...

  5. Cathodic protection - Wikipedia

    en.wikipedia.org/wiki/Cathodic_protection

    Cathodic protection (CP; / kæˈθɒdɪk / ⓘ) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. [1] A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode. The sacrificial metal then corrodes instead ...

  6. Solar cell - Wikipedia

    en.wikipedia.org/wiki/Solar_cell

    A solar cell or photovoltaic cell (PV cell) is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. [1] It is a form of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is exposed to light.

  7. Direct current - Wikipedia

    en.wikipedia.org/wiki/Direct_current

    Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction ...

  8. Electric power transmission - Wikipedia

    en.wikipedia.org/wiki/Electric_power_transmission

    Two additional circuits are obscured by trees on the far right. The entire 6809 MW [ 1 ] nameplate generation capacity of the dam is accommodated by these six circuits. Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation.

  9. Power inverter - Wikipedia

    en.wikipedia.org/wiki/Power_inverter

    Inverter designed to provide 115 V AC from the 12 V DC source provided in an automobile. The unit shown provides up to 1.2 amperes of alternating current, or enough to power two 60 W light bulbs. An inverter converts the DC electricity from sources such as batteries or fuel cells to AC electricity. The electricity can be at any required voltage ...
